First of all I'm not an Expert in Ubuntu.

I am using Ubuntu 14.04.4 on my Dell Inspiron 11 3147. Since Ubuntu 14.04.4 Released, it's freezing frequently. Especially when I'm Browsing the Internet (I'm currently using Opera but I tried Chrome and Firefox too). It was okay when I was using 14.04.3. But the Latest Version is totally Freezing my Laptop (Even Mouse doesn't work). I tried Magic SysRq Key Combination (Alt + SysRq + REISUB) but nothing happens. What can I do to fix this Problem?

Thank You!

P.S. I fresh installed 14.04.4 when it Released. And the Same thing happens on Ubuntu 15.10 too.

An Atom processor? Running Ubuntu??? :O

I'd start looking at Lubuntu and install that!

Probably your system was just barely fitting until 14.04.4 when it started swapping like mad and that just looks like it's freezing: it's actually still working, but 1000 times slower then before...

Sorry to be the harbinger of bad news...

Alternatively, just get rid of that thing and buy a new computer instead of using Lubuntu (which I've ran on Atom processors a long time ago, though not recently)
